Antivirus companies are warning of new malicious software that can infect any cell phone capable of running Java applications, not just feature-rich smartphones. The Trojan horse was first spotted by Moscow-based Kaspersky Lab, which calls it RedBrowser. The malicious code poses as an application that promises people the ability to visit mobile Internet sites using text messages instead of an actual Net connection, Kaspersky said in a statement Tuesday. Instead, the Trojan <A HREF="http://news.zdnet.com/2100-1009_22-6044266.html?tag=zdnn.alert">sends messages to certain premium rate numbers</A> that charge between $5 and $6 per message, Kaspersky said. That could drive up the text message bill for mobile phone users in Russia on the Beeline, MTS, and Megafon networks.
